Persistent Left Superior Vena Cava: Implications of Surgical Management

11 UCLA-Kern Medical, Bakersfield, CA, USA.
Summary
Persistent left superior vena cava, a common congenital anomaly, was incidentally found in a patient with heart failure. This condition requires special considerations for advanced cardiac device placement and transplantation.
Area of Science:
- Cardiology
- Congenital Anomalies
- Thoracic Venous Return
Background:
- Persistent left superior vena cava (PLSVC) is the most common congenital anomaly of thoracic venous return.
- It arises from the failure of the left anterior cardinal vein to regress during embryonic development.
Observation:
- A 41-year-old male presented with congestive heart failure exacerbation.
- An incidental finding during evaluation was a persistent left superior vena cava.
Findings:
- The patient required implantable cardioverter defibrillator placement.
- Cardiac transplantation assessment was also indicated.
Implications:
- PLSVC necessitates specific clinical considerations for advanced device implantation.
- Centers performing cardiac transplantation must be prepared for potential right-sided approaches and transplantation irregularities in patients with PLSVC.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

435
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

01:14Cranial Bones: Superior and Posterior View
5.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Anatomy of the Heart
119.5K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

02:03Anatomy of the Circulatory System
97.8K
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
